Best way to migrate from Windows 2003 SMB to 2008 standard domain controller

I would like to know the best way to migrate from Windows 2003 Small Business Server (Domain Controller) to Windows 2008 Standard. I want to migrate to 2008 and decommission the 2003 server and re-purpose that server. What is the best path to take and what tests do I need to perform on the domain before I do the migration?

Assuming you aren't running Exchange on that server as well, you should be able to join the 2008 server to the domain. The SBS server will complain, but it isn't going to stay, so that shouldn't be an issue. Once the SBS server is out of the picture, upgrade your domain functional level.

1) Build your 2008 install.
2) Give it a static IP
3) dcpromo into the network (dcpromo /domainprep and /forestprep first)
4) Transfer all the roles to the 2008 machine (use fsmt tool)
5) Kill the old server (Dcpromo it out of the domain)

One thing I must note is that they are not using Exchange for their mail so that is one thing I don't have to deal with.

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

You can just bypass the Exchange process in  the link

This seems pretty straight forward, seems, but I will have to start the process and see what happens. I am concerned that the AD is broken but won't know until I run the tests.

The first comment in this thread isn't even close to being correct.  If you follow the process provided then it will without doubt kill your domain.

Follow my guide provided by dariusg, it's tried and tested.

Also...I single server (small business server) domain environment can't be that dead so, do the checks outlined in my guide BEFORE you start.  If they bring any erros up then raise a question to get them solved.

A common mistake is starting the migration before you fix these errors

I will take you advice into account Demazter. I wasn't planning on using the first comments however I could see them working in a basic setting but will be using your outline to do the migration. The server is kind of sick but haven't started the troubleshooting so I don't know how sick. I will make sure to have all issues resolved before starting the migration because I cannot have a problem with this client. Thanks again for your outline and suggestions.
